The compressive strength of gypsum specimens with an average density of 600 kg/m 3 in dry state is between 15 and 25 MPa, when building gypsum strength is 5 MPa, when initial building gypsum strength is 10 MPa, gypsum specimens strength increases up to 30–40 MPa (Ferronskaya ...
Plaster, the traditional wall covering before gypsum board was available, has compressive strength similar to concrete -- more than 2000 psi. Veneer-coat plaster can be spread and finished over gypsum boards for added strength and durability. The coating can reach compressive strength up to 4000 psi within a few days of installation.
However, there are two major differences between plaster and drywall. Plaster is a product not much different than concrete. Once dry and cured, plaster can develop a compressive strength of more than 2,000 pounds per square inch. Drywall does not even come close to this number.
